Muzzle trashed...

Scrub it well as suggested. Try shooting it and see how it does, it may surprise you(one way or the other). You can ask S&W about replacing the barrel (they may, but I doubt it). Or just see if you can find a ported barrel for it and replace it. Keep us posted.
 
the ez shot ok,... at 15 yards, not great, could be sights, prob. me, first 25 rounds, and not sure if the barrel was going to come apart in my hands. No excuses, prob. me... Its not a target pistol, fairly smooth shooter,. I dont really get the ported barrel part but shot ok with a trashed muzzle.

yes and yes,....Monarch 94gr FMJs w polymer coating and steel casings, 14.00 worth. If you mean, does the damage seem worse:?.... not really.
 
hard to see the depth looks like crud to me. re crowning the muzzle will clear that up and is far cheaper than a new barrel or just shoot it
 
Do most machine shops re crown barrels? where would I get a price on a re crown? That would cut down the barrel past the port. 3/8" at least. Would not that effect accuracy as much as the damage? maybe more?

I have a theory, but there's no way to prove it.

Somehow, a kid or group of kids got hold of this gun and a package of Black Cats. He/They then proceeded to stick firecrackers into the muzzle and light them to make a noise and smoke just like a loaded gun. When the fun was over, (out of firecrackers) the gun was returned to its original storage location and the black powder fouled bore was not discovered by the owner until after severe corrosion had set in. A cleanup attempt would have cleared out the rust but left the damage from pitting.

Just a theory. :)
 
As noted above, I think this is shooting residue (although some areas look pitted?). A gun that badly neglected with rust would be rusty everywhere and reddish brown, plus you mentioned carbon fouling in other areas.

I'd suggest a long soak of the muzzle in solvent followed by a serious scrubbing.
 
Hey Gang,... those of you still following the saga of the pitted barrel... must be riveted by now!. Another tech at S&W looked at the images and also said, it was lead build up that often happens on ported barrels. Recommended "Kleenbore Lead Away:", to remove. Maybe someone has used it,... review time! Plus, and this is the kicker,... there is a recall on this gun. It falls in the date range during covid,(mid year of 2020) of a bad batch of hammers with cracks that could release from the sear and go into full auto mode, sometimes without touching the trigger.... so its gotta go in anyway. Thanks to all that commented, and Ill post on progress at a future date....

MD,... I think you may be correct sir. Please see my most recent post,... as a tech at SW agrees with ya, as well as a couple others on this thread. Its been soaking since yesterday afternoon in sta-bil gun clp... we will see if it has the kahonies to remove the build-up/. if not, its #9 this after...
 
It not just buildup of carbon, lead....There is damage and the worst pitting (biggest crater) is just opposite the port. The port had effect on what ever chemical process caused the damage. There is definite metal missing... like to know what they were shooting.
 
more images, check out the band where the rifling stops and the ported area starts. this is after overnight soaking and an afternoon of scrubbing...
